This investigation was carried out during 4th November 2019 to 20th April 2020 at Grdarasha field, college of Agricultural Engineering Sciences-Salahaddin University, to evaluate the effect of foliar application of the Nitrophenolates biostimulator at different levels (0, 0.2, 0.4, 0.6, 0.8 and 1 ml.l-1)on growth and yield of two Pea cultivars (Utrillo and Nihal). Significant results were obtained from most studied parameters. The results indicated that cultivars had significant response on some of vegetative growth and yield parameters of pea, the best results were recorded from Utrillo cultivar. Moreover, foliar spraying of Nitrphenolates had significant influence on vegetative parameters, the highest significant result of leaves and branchesnumber (110.747 and 2.694 respectively) were recorded from (1ml.l-1). While, the best results of vegetative growth fresh weight and leaf chlorophyll content were obtained from 0.2 ml.l-1treatment. Foliar spray of Nitrphenolate also increased significantly yield parameters, where the highest values of number of seeds.pod-1, yield per plant, plat and hectare (6.000, 0.168kg, 1.009kg and 1.681ton respectively) were recorded from 0.2 ml.l-1 treatment compared with the control. Meanwhile, there was the significant response of cultivars to foliar application of Nitrophenolates on most vegetative growth and yield components and were recorded for both cultivars especially Nihal.
